Train can be worse for climate than plane | New Scientist
A new study compares the “full life-cycle” emissions generated by 11 different modes of transportation in the US. Unlike previous studies on transport emissions, Mikhail Chester and Arpad Horvath of the University of California, Berkeley, looked beyond what is emitted by different types of car, train, bus or plane while their engines are running and includes emissions from building and maintaining the vehicles and their infrastructure, as well as generating the fuel to run them. (Table 1 on page 3 has a complete list of components that were considered).

Holly was inspired by the actions of Greta Thunberg, who in September sat outside the Swedish parliament for three weeks on “school strike”. International interest in her story led to Thunberg going to Davos last month to address world leaders. While she travelled for 32 hours on trains to reach the ski resort, political and business leaders hired 1,500 private jets to get to the summit.

Every Study Ever Conducted on the Impact Converting Street Parking Into Bike Lanes Has on Businesses - CityLab
But here's the thing about the "studies on possible economic impacts" requested by retailers on Polk Street, or really wherever bike-lane plans emerge—they've been done. And done. And done again. And they all reach a similar conclusion: replacing on-street parking with a bike lane has little to no impact on local business, and in some cases might even increase business. While cyclists tend to spend less per shopping trip than drivers, they also tend to make more trips, pumping more total money into the local economy over time.

Shenzhen's silent revolution: world's first fully electric bus fleet quietens Chinese megacity | Cities | The Guardian
Shenzhen now has 16,000 electric buses in total and is noticeably quieter for it. “We find that the buses are so quiet that people might not hear them coming,” says Joseph Ma, deputy general manager at Shenzhen Bus Group, the largest of the three main bus companies in the city. “In fact, we’ve received requests to add some artificial noise to the buses so that people can hear them. We’re considering it.”

The benefits from the switch from diesel buses to electric are not confined to less noise pollution: this fast-growing megacity of 12 million – which was a fishing village until designated China’s first “special economic zone” in the 1980s – is also expected to achieve an estimated reduction in CO2 emissions of 48% and cuts in pollutants such as nitrogen oxides, non-methane hydrocarbons and particulate matter.

Vos 10 propositions pour réduire l’addiction au carburant | L'interconnexion n'est plus assurée
Kérosène et zones commerciales. Mais on remarque aussi la taxation « du kérosène et du fioul maritime », ou encore l’arrêt de « la construction de zones commerciales autour des villes ». C’est significatif. Ces deux débats ont émergé récemment. Jusqu’au milieu des années 2010, la taxation du kérosène et du fioul, carburant des avions et des navires internationaux qui échappent encore aujourd’hui à tout impôt, n’était avancée que par quelques militants écologistes. Cette proposition, que soutient également l’auteur de cette tribune dans Le Monde, est en revanche vigoureusement rejetée par la ministre des transports.

Quant aux extensions et créations de zones commerciales, qui écrasent les villes moyennes et petites (lire ici), elles échappaient jusqu’à présent à tout débat public. Pour un maire, ceci relevait (et relève encore, pour bon nombre d’entre eux) d’un aveugle « développement économique », sans discussion possible.

A view from the cycle path: electric cars
It made me think: what exactly have we bought today ? Our tank full of fuel came to a bit more than 36 and a half litres. 36.5 l of petrol weighs about 26 kg. Burning that one tank full of petrol will put about 84 kg, a little more than my own weight, of CO2 into the air. That's the effect from just one tank full of petrol, which according to the manufacturer is supposed to be enough to drive around 500 km.

Petrol is amazing stuff. It has an energy content of 9.7 kWh per litre, so today we bought 355 kWh of energy for our 53 euros. The car consumes about 0.7 kWh produces 0.17 kg of CO2 per km driven.

A few years back, someone who set a world record by cycling over 1000 km in 24 hours calculated that his average power output was about 115 W for the entire 24 hours. That's someone at the absolute peak of what is possible, and his body generated about 2.7 kWh over a 24 hour period.

In light of this, I think it's reasonable to say that an averagely strong person doing an 8 hour shift at a physically demanding job would expend no more than 1 kWh per day at work, so we could say that in our tank full of petrol we've bought the equivalent of someone working hard nearly every day for an entire year, including weekends and almost all holidays. This cost just 53 euros. That really is a bargain.

"J'ai craqué, j'ai repris la voiture" : des usagers du train racontent ce qui les a contraints à renoncer
Et alors quand vous avez des contraintes horaires avec l'assistante maternelle qui garde votre enfant, je ne vous en parle même pas", poursuit-elle. Marion raconte qu'en 2016, alors qu'elle habitait à Cazaux, village près du bassin d'Arcachon (Gironde), elle a choisi de reprendre ses études. "Pour aller à la fac, je prenais ma voiture jusqu'en gare de la Teste-de-Buch et par souci d'économie, je la laissais sur le parking pour prendre le TER jusqu'à Bordeaux. Sauf que les trajets quotidiens en TER dans ce coin-là sont un véritable enfer ! Des travaux tout le temps et surtout des retards et des trains supprimés constamment car les voies ont été mal entretenues."

Sur ce point, la SNCF met en avant "l'effort sans précédent des régions en faveur du renouvellement des TER". "La grande vague de travaux lancée depuis plusieurs années sur le réseau, afin de le moderniser après une trop longue période de sous-investissement, continue", affirme-t-elle. Avant de reconnaître : "Leur rythme soutenu ne permet pas de les faire uniquement de nuit et peut parfois impacter les circulations quotidiennes."

How the Koch Brothers Are Killing Public Transit Projects Around the Country - The New York Times
The group, the local chapter for Americans for Prosperity, which is financed by the oil billionaires Charles G. and David H. Koch to advance conservative causes, fanned out and began strategically knocking on doors. Their targets: voters most likely to oppose a local plan to build light-rail trains, a traffic-easing tunnel and new bus routes.

“Do you agree that raising the sales tax to the highest rate in the nation must be stopped?” Samuel Nienow, one of the organizers, asked a startled man who answered the door at his ranch-style home in March. “Can we count on you to vote ‘no’ on the transit plan?”

La ZTL italienne, injustement méconnue. Il existe un autre outil, beaucoup trop méconnu en France, qui permet de sélectionner les automobiles non pas en fonction de leur niveau de pollution, mais de leur usage. Ce sont les zones à trafic limité (ZTL), instaurées dans pratiquement toutes les villes d’Italie, des plus grandes aux plus petites. Si chaque pays dispose de son organisation ad hoc, dont l’Ademe a établi un inventaire, celle qui prévaut en Italie présente de nombreux avantages.

C'est vertigineux. Et le défi, c'est de faire tout ça sans dépenser trop et en gênant le moins possible la circulation des trains. Les travaux vont donc avoir lieu de jour et en semaine entre Clisson et La-Roche-sur-Yon (ce qui va permettre d'économiser 15 millions d'euros par rapport à des travaux de nuit). C'est là que ce sera le plus embêtant. Pendant trois mois, du 7 janvier au 29 mars, tous les trains de la journée, entre 8h30 et 17h, seront remplacés par des cars. C'est-à-dire neuf TER, quatre Intercités et deux TGV. Ceux des heures de pointe, le matin et le soir, circuleront mais ils rouleront un peu moins vite. Le trajet Nantes-La Roche durera 8 minutes de plus. Les abonnés seront prévenus dans les jours qui viennent des nouveaux horaires.

'I leave the car at home': how free buses are revolutionising one French city | Cities | The Guardian
One month ago, Dunkirk – with a metropolitan population of 200,000 – became the largest city in Europe to offer free public transport. There are no trams, trolleybuses or local commuter trains, but the hop-on-hop-off buses are accessible and free – requiring no tickets, passes or cards – for all passengers, even visitors...
Vergriete believes this is all part of an erroneous received dogma. He admits free public transport may not work everywhere, but says that, as well as being good for the environment, it is a social measure, a gesture of “solidarity” and promotes a more egalitarian redistribution of wealth than tax cuts.
Get smart! How a 90s bus pass trial transformed London travel

“We have been pragmatic: we looked at the advantages of free transport and weighed them against the disadvantages and decided €7m is not a lot to pay for all the benefits. If I can pass one message to other mayors it’s to fight the dogma. Put the advantages and disadvantages on the table and consider it realistically. It may be that the financial cost is too great, but don’t underestimate the social advantages. You can’t put a price on mobility and social justice.”

Private hire vehicles might soon have to pay the London congestion charge. What difference would it make? – On London
However, CEPA study also anticipates that, as Mayor Khan acknowledged, PHV operators in the Central London area, who tend to be the larger firms, will respond to the loss of the exemption by distributing the bookings they receive differently among their drivers, resulting in a reduced number of drivers who’ve entered the charging zone picking up more passengers there than before and therefore spending more time than before on the area’s roads. That’s a big reason why CEPA’s calculation of the reduction in PHV traffic levels (6%) in the congestion charge zone, is much smaller than their calculation of the number of PHVs that would enter it (45%).

TfL concedes that the estimated one per cent reduction in traffic levels overall “appears modest”, but still contends that it would represent “an important step in managing and reducing congestion in Central London”, with consequential improvements in air quality too. But Gareth Bacon argued that any “very minor” reduction in congestion would also add to cumulative TfL policies enacted in the Mayor’s name, including hikes in licensing fees, that “are going to have an absolutely devastating impact on the private hire industry,” which has seen the number of firms licensed by TfL – as distinct from the number of drivers – fall in recent years, with smaller operators in particular disappearing

How E-Commerce Is Transforming Rural China | The New Yorker
Although China has the most Internet users of any country and the largest e-commerce market in the world—more than twice the size of America’s—there are still hundreds of millions of Chinese whose lives have yet to migrate online. Analysts predict that China’s online retail market will double in size in the next two years, and that the growth will come disproportionately from third- and fourth-tier cities and from the country’s vast rural hinterland. At a time when the Chinese government has instituted monumental infrastructure programs to develop these regions, companies like JD are providing a market-driven counterpart, which is likely to do for China what the Sears, Roebuck catalogue did for America in the early twentieth century.

Why is London’s public transport being used less? – On London
use of the Tube has been falling for the first time in many years. But, of course, it might not be good news for the city as a whole. The same goes for the recent drop in passenger numbers on most suburban rail services in and out of the capital and the decline in bus ridership since 2014/15. High and rising public transport use has long been regarded as a sign of London’s economic health and the triumph of its mass transit modes over the private car. What do these interruptions in long-term upward public transport trends mean?

Emissions data has placed transport as the new king of climate-warming pollution at a time when the Trump administration is reviewing or tearing up regulations that would set tougher emissions standards for car and truck companies. Republicans in Congress are also pushing new fuel economy rules they say will lower costs for American drivers but could also weaken emissions standards.

Yee believes that his legislation is the “first and most restrictive” of its kind. Robot permits will be capped at three per company, and nine total at any given time for the entire city. The robots will now only be allowed to operate within certain industrial neighborhoods, on streets with 6ft-wide sidewalks, and must be accompanied by a human chaperone at all times.

Does Elon Musk Understand Urban Geometry? — Strong Towns
The reigning fantasy of Musk’s argument is that we must always “take people all the way to their destination.” To do this we must abolish the need to ever change vehicles — from a train to a bus, from a car to a train, from a bus to a bike — and of course we also abolish walking. This implies a vision in which buses are shrunk into something like taxis, because a vehicle going directly from your exact origin to your exact destination at your chosen time won’t be useful to many people other than you.

So a bus with 4o people on it today is blown apart into, what, little driverless vans with an average of two each, a 20-fold increase in the number of vehicles? It doesn’t matter if they’re electric or driverless. Where will they all fit in the urban street? And when they take over, what room will be left for wider sidewalks, bike lanes, pocket parks, or indeed anything but a vast river of vehicles?

There and Back Again | The New Yorker
Seven hours is extraordinary, but four hours, increasingly, is not. Roughly one out of every six American workers commutes more than forty-five minutes, each way. People travel between counties the way they used to travel between neighborhoods. The number of commuters who travel ninety minutes or more each way—known to the Census Bureau as “extreme commuters”—has reached 3.5 million, almost double the number in 1990. They’re the fastest-growing category, the vanguard in a land of stagnant wages, low interest rates, and ever-radiating sprawl. They’re the talk-radio listeners, billboard glimpsers, gas guzzlers, and swing voters, and they don’t—can’t—watch the evening news. Some take on long commutes by choice, and some out of necessity, although the difference between one and the other can be hard to discern. A commute is a distillation of a life’s main ingredients, a product of fundamental values and choices. And time is the vital currency: how much of it you spend—and how you spend it—reveals a great deal about how much you think it is worth.

Airplanes, airports, and air travel have contributed to our geographic spikiness, fueling the growing concentration of population and economic activity in a small number of large, productive, and well-connected superstar cities.

That’s one of the key findings of a recent study on the effects of global airports and air connectivity on economic and urban development. The study, by economists at Harvard University’s Kennedy School of Government and the University of Zurich, examines air travel’s role in the economic performance of more than 819 cities and metro areas in 200 different countries. Using detailed data from the International Civil Aviation Organization, it looks specifically at how direct flights facilitate business links and investments between pairs of cities, with data on over half a million businesses and more than 30,000 major business events around the world.

A short-term intervention study - Impact of airport closure due to the eruption of Eyjafjallajokull on near-field air quality - Research Portal, King's College, London
We show that the airport closure resulted in an unambiguous effect on NOx and NO2 concentrations close to the airport, even though the ban only lasted six days. Furthermore, we estimate the annual impact airport emissions have on mean concentrations of NOx and NO2 for different years and compare these estimates with a detailed dispersion modelling study and previous work that was based on the analysis of monitoring site data. For the receptor most affected by the flight-ban approximately 200 m south of the airport we estimate the airport contributes about 13.5 mu g m(-3) NOx (approximate to 23% of the total measured NOx concentration), which is similar in magnitude to detailed dispersion modelling estimates of 12.0 mu g m(-3), but approximately twice that of other estimates based on the analysis of ambient measurements. Other measurement sites showed more mixed results due to the prevailing meteorology at the time of the ban, which affected the extent to which these sites were affected by the flight-ban.

Why your next bike should be a touring bike | road.cc
Good article. My only disagreement is over its promotion of front racks and panniers. They're best avoided, though if you're planning a tour with family, I guess you'll have to accept the additional burden. Front panniers suck aerodynamically, and the heavier steering tires the upper body significantly. There's no need to weight the front of the bike to keep the front wheel on the ground going uphill, even if you're fully loaded at the back.

How to keep your gear down to two rear panniers, a rackbag, and a wee barbag is a separate article, but it can be done.

A l’étranger, l’évaporation du trafic est une réalité - Le Parisien
A l’Institut d’aménagement et d’urbanisme d’Ile-de-France (IAU), on étudie depuis plus de 10 ans l’impact de la fermeture de voies rapides urbaines dans le centre des grandes villes, dans le monde entier. Et les résultats, unanimes, sont surprenants.

« En dépit des craintes initiales, la suppression de voies rapides n’engendre pas de dégradation des conditions de circulation au-delà des ajustements de départ, explique Paul Lecroart, l’urbaniste de l’IAU spécialiste de la question. Dans toutes les villes étudiées, l’évaporation du trafic est importante ». Pas encore à Paris, certes. Mais dans la douzaine de métropoles étudiées, aux Etats-Unis, au Canada ou en Corée du Sud, cela ne fait pas de doute. Paul Lecroart cite une étude anglaise, très documentée, portant sur 60 villes, qui calcule que, quand une voie rapide est supprimée, le trafic global diminue en moyenne de 14% après plusieurs mois.

Why don't UPS drivers turn left? — Quartz
UPS have moved away from trying to find the shortest route and now look at other criteria to optimize the journey. One of their methods is to try and avoid turning through oncoming traffic at a junction. Although this might be going in the opposite direction of the final destination, it reduces the chances of an accident and cuts delays caused by waiting for a gap in the traffic, which would also waste fuel.

UPS have designed their vehicle routing software to eliminate as many left-hand turns as possible (in countries with right-hand traffic). Typically, only 10% of the turns are left turns. As a result, the company claims it uses 10 million gallons less fuel, emits 20,000 tonnes (22,000 tons) less carbon dioxide, and delivers 350,000 more packages every year. The efficiency of planning routes with its navigation software this way has even helped the firm cut the number of trucks it uses by 1,100, bringing down the company’s total distance travelled by 28.5 million miles—despite the longer routes.

No prizes for originality  |  JOHN DALES - Urban Movement
Enabling more and more traffic to go by road will do yet more damage to our towns and cities. But how does wise government go about dealing with this problem? The wise response, surely, is neither simply to bow to the wishes of individuals nor to insist that they use alternatives that are, or are considered, inconvenient. It is to make the more benign alternatives to private car travel more convenient. Or, put another way, better.

THAT is what we should be investing in.

Sir John Kingman, chairman of the Wolfson prize judging panel, correctly observes that, “The biggest challenge for policy makers in this area is not technical or financial, it is political – how to convince the public that there is a better way.” He goes on to say that, “The judges will be particularly interested in fresh thinking around this”

Le véhicule électrique doit être utilisé intensément pour maximiser le gain environnemental
Au plan énergétique, "la consommation (…) d'un VE est globalement proche de celle d'un véhicule diesel", relève l'Ademe. Car si sa chaîne de traction présente un excellent rendement énergétique, celui de la production électrique nécessaire pour recharger ses batteries est faible. En revanche, l'avis souligne l'intérêt du VE concernant la réduction de la dépendance au pétrole importé, d'autant plus que le mix électrique intégrera une part croissante d'énergies renouvelables (EnR). Un avantage qui se traduit économiquement par une baisse de la facture énergétique et, au plan environnemental, par une moindre sollicitation des ressources fossiles.

Le VE a des impacts négatifs sur l'environnement en termes d'acidification des milieux et d'eutrophisation des eaux, lors de sa phase de fabrication principalement. "Sur le cycle de vie du véhicule, ces impacts sont toutefois du même ordre de grandeur pour un VE que pour un véhicule thermique", affirme l'Ademe. Mais, celle-ci ne parle pas des matériaux nécessaires à la production des batteries des VE, notamment le lithium et les terres rares. L'avis souligne en revanche que l'utilisation en seconde vie et le recyclage des batteries permettent de diminuer ces impacts environnementaux.

“The True Costs of Automobility: External Costs of Cars” | Road Danger Reduction Forum
Anyway, the amount of taxation raised by UK motorists – fuel duty and its associated VAT along with vehicle excise duty contribute around £38bn a year – is £10 billion less than the £48 billion estimated by the report’s authors to be the external costs of motoring.

And don’t forget that those costs do not include the health disbenefits to drivers, congestion, danger, visual intrusion, community disruption (with loss of children’s independent mobility), policing and road building, and parking space costs.

If anything one can argue that they are a significant underestimate.

Ford Is Finally Thinking Beyond Cars
Ford is working with design firm Ideo to envision the post-car generation of mobility. You know Ideo—the company that designed Apple’s first mouse and laptop, and even Ford’s interactive dashboards, through a proprietary process that the company calls “design thinking.” Right now, Ideo is hard at work for Ford in London, Shanghai, and Chicago, prototyping new products and services that might be as world-changing as personal motorized vehicles were in 1896.

In a narrative that sometimes reads like an Onion article, the NYT peeks into Ideo’s Chicago-based lab where designers assign themselves various tasks in order to test the city’s transportation options. One example: Get to a restaurant four miles away within 45 minutes while carrying heavy shopping bags, spending only $10 for three people.

Revealed: Oil giant Exxon lobbied against decarbonisation and electrification of EU transport - Energydesk
The current carbon price of 8 euros per tonne could correspond to adding only approximately 1.6 eurocents to the price of a litre, given that each litre of fuel would produce just under 2 kilos of CO2, according to a back-of-envelope calculation.

Analysts say the carbon price will be around 19 euros per tonne in 2020. At this rate, additional duty would be 3.8 euro cents per litre, adding up to only 15 cents for a 40 litre fill up.

Even if the policy were meaningful, it would be almost impossible to implement at EU level since fiscal measures are decided unanimously.

Le grand défi de la mobilité durable
Les transports pris dans leur globalité représentent un quart des gaz à effet de serre produits aujourd’hui… dont 1% seulement pour les modes collectifs. En France, le transport public urbain représente seulement 2% de la totalité de l’énergie utilisée par le secteur du transport (contre 50% par les voitures). Notre défi majeur est donc de convaincre – sans les contraindre - les gens de laisser leur voiture au garage. Qualité de l’offre, confort des véhicules, services digitaux pour attirer les voyageurs et prix raisonnables peuvent favoriser le report modal de la voiture particulière vers les transports collectifs.

If you think roads are clogged now, wait till the self-driving cars arrive - The Washington Post
While driving is up in 2015, it’s nothing compared with the explosion in vehicle traffic we’re in for by 2050, according to a new report from KPMG. It estimates that between population gains and the popularity of fully self-driving mobility services, we’ll see the total number of vehicle miles grow by 1 trillion. (Half of the 1 trillion it attributes to population growth.) For perspective, U.S. residents drove 3.1 trillion miles in 2014.

KPMG expects this growth to come from trips taken by the very young and very old, who can be immobile only due to their inability to drive. By having access to a self-driving shuttle, a world of opportunity would open up.

he bus maneuvers with the help of cameras, laser radars, and a master controller that tells it to go faster and stop at signals. Yutong says in a press release it masterfully handled the road during one of its test drives:

With a distance of 32.6 km, the intercity road from Zhengzhou to Kaifeng has 26 traffic lights in total. Despite this and busy traffic, Yutong driverless bus successfully completed a series of highly complex driving acts, such as automatic lane change, overtake, and responding traffic lights. Without any human assistance, the bus arrived at its destination with its highest speed reaching 68 km/h (42 mph). According to some experts, the much improved active safety standard is the biggest advantage of unmanned vehicles as they are very likely to eliminate all kinds of traffic accidents.

Study finds only 44% of people in England capable of getting to work by walking or cycling - University of Leeds
Most people in England could not get work without motorised modes of transport, according to new research by the University of Leeds.

Dr Ian Philips from the School of Geography modelled the capacity of individuals to complete journeys by walking or cycling in the event of a fuel shock.

The research found that capacity varies significantly depending on location – both at the district level and within districts.

The model results were also set in context against the Index of Multiple Deprivation (IMD), a UK government qualitative study of deprived areas at local authority district level, to provide an overall picture in the event of a fuel shock.

How much carbon emissions would robot taxis save? | Ars Technica
Jeffery Greenblatt and Samveg Saxena at Lawrence Berkeley National Laboratory, focus on autonomous taxis as having a viable business model. Many users and frequent trips make up for higher purchasing costs; indeed they point to Uber and Lyft as an analogous car-on-demand approach. While their paper looks at autonomous taxis, the calculations are mostly comparing current vehicle efficiencies with predictions for 2030. The benefits of being autonomous (as opposed to human-driven) are assumed to come through more efficient allocation of vehicles—sending the right-sized vehicle to the right customer, balancing use across the fleet optimally, traveling in packs, and so on.

If we look at the big players in the Western press, such as the international New York Times or the BBC, they are all highly compromised organisations in terms of geo-politics, and in terms of their relationships with their own countries. It would be nice to live in a world where people didn't have to deal with an organisation that is not compromised in any manner whatsoever, but we don't live in that world. People have to use cars and they have put to petrol in their cars, and that petrol is made by Shell or BP.

Every Study Ever Conducted on the Impact Converting Street Parking Into Bike Lanes Has on Businesses - CityLab
It's perhaps natural for a shop owner to fear that losing a parking space means losing revenue. Drivers tend to be wealthier than alternative transport users, and cars have big trunks to hold lots of stuff. Cities can add a bike lane and still keep street parking by bumping out spots from the curb (a common practice in New York), but generally speaking more road space for cyclists means less for cars.
But here's the thing about the "studies on possible economic impacts" requested by retailers on Polk Street, or really wherever bike-lane plans emerge—they've been done. And done. And done again. And they all reach a similar conclusion: replacing on-street parking with a bike lane has little to no impact on local business, and in some cases might even increase business. While cyclists tend to spend less per shopping trip than drivers, they also tend to make more trips, pumping more total money into the local economy over time.

Murder Machines: Why Cars Will Kill 30,000 Americans This Year | Collectors Weekly
By the end of the 1920s, more than 200,000 Americans had been killed by automobiles. Most of these fatalities were pedestrians in cities, and the majority of these were children. “If a kid is hit in a street in 2014, I think our first reaction would be to ask, ‘What parent is so neglectful that they let their child play in the street?,’” says Norton.

“In 1914, it was pretty much the opposite. It was more like, ‘What evil bastard would drive their speeding car where a kid might be playing?’ That tells us how much our outlook on the public street has changed—blaming the driver was really automatic then. It didn’t help if they said something like, ‘The kid darted out into the street!,’ because the answer would’ve been, ‘That’s what kids do. By choosing to operate this dangerous machine, it’s your job to watch out for others.’

Who pays for roads? – I Pay Road Tax
Motorists pay for roads, yes? No. All tax payers pay for roads, not just motorists. Those who pay income tax and those who pay council tax are the ones who pay for roads, and that’s not just motorists. And anybody who buys anything in Britain also helps to pay for roads because VAT also contributes to the national coffers. Businesses which pay business rates also contribute into the national coffers. And that’s where the money for roads comes from: the consolidated fund, the treasury’s pot of cash that pays for everything. No taxation in the UK is ring-fenced i.e raised by one set of users, and spent on that set of users. But what about ‘road tax’? Clearly, the name says it all, you might think, it’s a tax that pays for roads! Sorry, no, ‘road tax’ doesn’t actually exist. It was abolished in 1937, along with the ‘road fund licence’. It’s now car tax, a UK tax on tailpipe CO2 emissions above 100gm per km*. It’s not now, and never has been, a fee to use roads.

If You Can't Beat 'Em, Join 'Em
Using a car to get into the centre of a British city is like using a sledgehammer to crack the proverbial nut. It wouldn’t be so bad if the one-tonne SUVs tootling around were carrying the seven people they’re designed to carry but more often than not they’re transporting just a solo driver. This is an enormous waste of precious resources. Petrol might be getting cheaper but city rents aren’t. Land is scarce making it expensive, yet so much of it has been given over to slow-moving lumps of metal that take up inordinate amounts of costly city space per human traveller. Now, this is a motoring website, so where’s the twist? There isn’t one. Consider this a reality check. In your future, and in mine too, there will be fewer facilities for travelling everywhere by car. The nooks and crannies are already slowly being closed off to motor cars, and the generous number of carriageways will also be slowly reduced. Roadspace reallocation will be done stealthily – just as frogs don’t jump out of water boiled from cold, you may not notice until it’s too late. In fact, such “filtered permeability” for users other than private motor cars has been happening for some years but at such an under-the-radar level it may have passed you by.

How Driverless Cars Could Make Traffic Dramatically Worse - CityLab
A new simulation-based study of driverless cars questions how well these two big secondary benefits—less traffic and more comfort—can coexist. Trains are conducive to productivity in large part because they aren't as jerky as cars. But if driverless cars mimic the acceleration and deceleration of trains, speeding up and slowing down more smoothly for the rider's sake, they might sacrifice much of their ability to relieve traffic in the process.

The value of a bicycle after SHTF | Prepper-Resources.com - The Ultimate Prepper & Survivalist Blog.
Your BugOut location is 100 miles away and after SHTF the roads are absolutely gridlocked making driving out impossible. You could walk out with your family but that means you now have to carry all of your BugOut gear on your back. This increases your minutes per mile to something like 20 to 30 (especially if you have kids). At 20 minutes/mile it would take you 33 hours to walk to your BugOut location. Realistically that would translate into about 6 days as moving under heavy loads with your family would probably limit you to 5-6 hours of walking per day.

Now let’s factor in the use of a bicycle. Typical speed on bicycles are 10 to 20 mph so we’ll split that down the middle at 15mph. Instead of taking 10 hours to walk home from your job after SHTF it now would take 2 1/2 hours to ride. Instead of taking around 6 days to walk to your BugOut location you could ride there in 6 1/2 hours (or maybe take 2 days factoring in fatigue). The point here is a bicycle should be standard on every prepper’s “must have” list.

The Real Reason U.S. Gas Is So Cheap Is Americans Don't Pay the True Cost of Driving - CityLab
what would gas taxes look like if they reflected the true social cost of driving? It's no easy question to answer, but for some sense of one we turn to economist Stefan Tscharaktschiew of the Dresden University of Technology, who recently tried to calculate the "optimal" fuel tax for Germany. His goal was to find a number that not only reflected all the social impacts of driving, but also one that accounted for changes in behavior that would result from more expensive gasoline.

After crunching the numbers, Tscharaktschiew reached an optimal gas tax of .96 euros per liter—a figure that amounts to more than $4.36 a gallon in American money. Mind you, that doesn't include the actual market cost of gasoline. ...
Michael Specter of the New Yorker may have put it best when he likened cheap gas to "an industrial form of crack": impossible to quit, no matter the damage it causes.

The "fundamental rule" of traffic: building new roads just makes people drive more - Vox
city planners and traffic engineers have long acted on the belief that adding road capacity will reduce traffic. But no one had ever tested this idea empirically. One reason is that it's a difficult thing to analyze. Researchers can't exactly conduct a controlled study, giving randomly selected cities different amounts of road space simply for the purpose of an experiment.

So Turner and Duranton did their best to get around this by using a few novel methods. In an influential 2011 paper, they looked at the total capacity of highways in each metropolitan area in the US and compared it with the total number of vehicle miles traveled.

They found a one-to-one correlation: the more highway capacity a metro area had, the more miles its vehicles traveled on them.

Helsinki Has a Plan to Get People to Stop Owning Cars | Innovation | Smithsonian
Helsinki already has one piece in place. Last year it rolled out an on-demand minibus service called Kutsuplus (Finnish for “call plus”), and so far it’s living up to expectations.

Once people sign up for the service, they use their smartphones to order rides on the nine-passenger vehicle. They can also request a private trip at a higher fee. Then the system’s proprietary software kicks in, determining which of its 15 minibuses is in the best location to pick up and deliver a passenger to his or her destination. Adjustments are made throughout the day as buses are routed and rerouted around the city to provide the most direct routes for those who make requests. Since it works on the fly, the Kutsuplus system may have to do millions of calculations on a busy day to dynamically move buses around to service its customers. More than 13,000 people have now signed up.

Fees are more expensive than bus fares, but about half the price of taxis.

Chacun comprend que si chacune des treize ou quatorze millions de familles devait disposer ne serait-ce que 10 m de côte, il faudrait 140 000 km de plages pour que tout le monde soit servi ! En attribuer à chacun sa portion, c’est découper les plages en bandes si petites — ou serrer les villas si près les unes contre les autres — que leur valeur d’usage en devient nulle et que disparaît leur avantage par rapport à un complexe hôtelier. Bref, la démocratisation de l’accès aux plages n’admet qu’une seule solution : la solution collectiviste. Et cette solution passe obligatoirement par la guerre au luxe que constituent les plages privées, privilèges qu’une petite minorité s’arroge aux dépens de tous.
